Abstract

The spherical radio telescope uses a flexible cable net as the supporting structure. The main cable net is composed of a flexible main cable according to the short-range triangular mesh, and a reflection panel is installed on each triangular mesh. According to the adjustment method of spherical radio telescope reflection panel, this paper analyzes each reflection panel which constitutes a radio telescope. When the observation object is located just above the telescope, an ideal working parabolic optimization model considering the adjustment constraint of the reflection panel is established. The angle of the reflection panel is changed by adjusting the length of the cable under the main cable node, and then the shape of the panel plane is changed. The optimal working parabolic is obtained by using the golden section algorithm. When the position of the observation celestial body changes, the position of the working parabolic surface also changes with it. An optimization model of the optimal adjustment scheme of the main cable node is established to solve the optimal ideal working parabolic surface. For the morphological control problem of the main cable network, the telescopic amount of the actuator is planned and optimized, and the optimal control scheme is solved by using the improved butterfly optimization algorithm.
